Application

Resilient layer insulation - acoustic underlay system suitable for floors with floating screeds or between timber systems.

Made for the UFH systems to be easily installed.
Improved thermal efficiency as well.
Under screed.

Description

BIFLOOR is a 28 mm-thick under-screed panel designed to provide exceptional acoustic and thermal insulation for both residential and commercial spaces. Ideal for traditional concrete or brick-concrete slabs, as well as lightweight wooden floor structures, BIFLOOR is a versatile solution for new builds and renovations.

A key benefit of BIFLOOR is its seamless integration with underfloor heating systems. The panels feature an exclusive Velcro coating that allows heating pipes to be directly affixed, eliminating the need for metal grids and simplifying installation. This not only reduces installation time and costs but also ensures efficient system performance.

BIFLOOR panels are composed of a high-density polyester fiber sheet and a semi-rigid layer of SBR rubber granules, ensuring both mechanical stability and excellent acoustic performance, even at low frequencies. This makes them particularly effective for soundproofing wooden floors and creating comfortable living environments.
